Continuous-time identification for a class of switched linear systems

Abstract : In this paper, we propose an identification scheme for continuous-time switched linear systems with input-output form. The identification problem of such system consists in the estimation of parameters of the transfer functions of all sub-systems which constitute the switched system. To the best of our knowledge, no identification algorithm has been proposed for the identification of continuous-time switched linear systems. The proposed identification scheme is based on the use of an appropriate input sequence, sum of sinusoids, in order to reconstruct consistent sub-systems outputs. These consistent outputs are then used for the identification of parameter vectors of transfer functions of sub-systems. We show by some numerical simulations that the proposed identification scheme performs well.
